What are the reasons for the Chevrolet Cavalier not moving when in D gear?
2 Answers
The reasons for the Chevrolet Cavalier not moving when in D gear are as follows: 1. Torque converter: The torque converter shaft is locked, causing the fuel injection pump to stop working. 2. Lubricating oil: The lubricating oil passage is blocked, leading to insufficient lubrication, which results in the planetary gear carrier burning out. 3. Oil pump shaft: The oil pump shaft is broken, causing the oil pump to stop working or the differential to lack oil and burn out. 4. Transmission: The transmission oil pan is damaged, and all the transmission oil leaks out, causing vehicle issues. 5. Solenoid valve: The transmission valve body or solenoid valve is damaged and not working. 6. Loose linkage: The linkage or cable between the gear shift lever and the manual valve rocker arm is loose, keeping the manual valve in the neutral or parking position.
My Cavalier also experienced the issue of not moving when shifted to D gear last year, which really stressed me out at the time. Later, I found out it was because the transmission fluid hadn't been changed for too long, causing the deteriorated fluid to make the clutch plates slip. First, check if any warning lights are on the dashboard, especially the engine or transmission warning lights. Then try if other gears like R gear can move the car. If only D gear doesn't work, it might be due to a stuck transmission solenoid valve or a problem with the control module. An electronic parking brake not fully released can also lock the wheels, so remember to check the brake indicator light. It's best not to stomp on the accelerator forcefully - towing it to a repair shop to read the fault codes with a diagnostic computer is the most accurate approach. By the way, occasional jerking during cold starts is normal, but complete failure to move should be taken seriously.
